Simple Machines: Power

The video tutorial explains the concept of power by comparing the power of oxen and a tractor in plowing a field. It defines power as the rate at which work is done and introduces the mathematical formula for power: work divided by time. The tutorial further explains that power is measured in joules per second, also known as Watts, and provides practical examples to illustrate the concept, such as lifting a glass of water or the operation of a 100 Watt light bulb.
